Can Compact Fluorescent Light bulbs or UnityTM LED Bulbs be used outside in cold weather?

CF Bulbs are not recommended for use outdoors in temperatures below 5C and they tend to perform badly. Excessive warm up times, failure to start, and shortened life span are associated with using compact fluorescent bulbs in cold conditions, below 5C, and especially below OC. Some compact fluorescent bulbs available with special cold-weather ballasts, which may be rated to as low as -23°C (-10°F).

UnityTM LED Lights are well suited for use indoors and outdoors from -40C to +40C.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
